ADJUSTABLE GAGE ATTACHMENT FOR METAL-PERFORATING MACHINES.

SPECIFICATION forming part of Iietters Patent No. 688,479, datedDecember 10, 1901.

Application filed March 18, 1901. Serial No. 51,810. (No model.)

To all whom it Wmy concern:

Be it known that I, FRANK NATHER, o Johnstown, in the county of Oambriaand State of Pennsylvania, have invented a new and useful Improvement inAdjustable Gage Attachments for Metal-Perforating Machines, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, which form a part of this specification.

My invention relates to an adjustable gage attachment formetal-perforating machines, such as punches and drills, and is designedto provide means of simple, novel, and efficient character whereby apiece of metal may be accurately punched or drilled without previouslylaying outand marking the positions of the holes.' 1

My invention is particularly useful in connectionwithwork in whichcertain standard punchings or drillings are frequently used, as inrailway-rails and rail-sections, beams, channels, and other structuralshapes, but may be employed to advantage wherever the same character ofpunching or drilling is used with sufficient frequency to justify themaking of the simple templets hereinafter described.

Genera'lly considered, my invention consists in the combination, with ametal-perforating machine, of an adjustable work-support, means foradjusting said support to shift the longitudinal center line' of thework transversely with respect to the perforatingtool, to therebydetermine and vary the position of the holes with respect to said centerline, interchangeable templets which govern the said adjustments inaccordance with the predetermined design or standard, and otherinterchangeable templets which are used to determine the location of theholes longit dinally in the work. I prefer also to give t e work-supporta second adjustment to adapt it to Work of difierent widths, whereby thesame machine and attachment may be used for various kinds of work. Inany case, however, where the work is confined to one varying type thissecondary adjustment is not a necessary feature of the invention.

My invention also consists in the novel construction, arrangement, andcombination of isometric perspective view of one'o'f the interchangeable templets removed from the work-support; Fig. 6, a sideView of a portion of the templet employed in connection with work ofconsiderable length; Fig. 7, a detail View of one of the templets whichcontrol the position of the work-support with reference to the punch,and Fig. 8 a detail view'of the adjustable pin used in connection withthe templet shown in Fig. 5.

The numeral 1 designates the overhanging arm of the frame of themachine, in which is mounted a vertically -reciprocating punchcarrier 2.r

3 designates a punch, and at an anvil-block, which is removably securedon the bed in the usual manner.

Secured to each side of the bed 5, in a manner which will be more fullydescribed hereinafter, is a bracket 6, formed with a guide- .way 7, inwhich is mounted one" of the supports now to be described. In thepresent instance each of these supports consists of two members orjaws(designated, respectively, by the numerals 8 and 9) whose bases arefitted to slide in the guideway 7. of these jaws is formed with athreaded bore to receive a rod or shaft 10, which has a righthand threadengaging the bore of the jaw 8 and a left-hand thread engaging the boreof the jaw 9. On each of the shafts 10 is a spiral or worm gear 11,which meshes with a corresponding gear on a connecting-shaft 13, whichis journaled in bearings on the jaw member 9. Those portions of theshafts 10 which carry the gears 11 are squared, and the gears aremounted to travel back and forth a limited distance on these squaredportions.

hand-wheel 14, by means of which the said The base of each On one end oftheshaft 13 is a' shaft may be actuated. It will be readily seen that byturning the said wheel in one direction the two jaws of eachwork-support may be brought together, as shown in Fig. 2, thus adjustingthem to receive a narrow piece of work, such as the T-rail shown indotted lines in said figure, while by turning the wheel in the oppositedirection said jaws or members may be separated to receive a wider pieceof work, such as the high-section girder-rail shown in dotted lines inFig. 4. The two threads of the rods or shafts 10 being of the samepitch, it is obvious that the jaws of each pair will move equaldistances to or from a given-center line with a given movement of thehand-wheel. As above indicated, in any case where but one style of workis to be done these adjustable jaws may be omitted and the work-supportat each side of the punch may be made in a single piece arranged toslide in the guideway 7. In most cases, however, it will be desirable toemploy the construction shown or its equivalent. The particular shape ofthe work-holding portion of the jaws may of course be varied by themechanic to suit the particular kind of work in hand.

Journaled in brackets on the vertical arm of the punch-frame is arock-shaft 16, to one portion of which is secured a handlever 17.Connected to the lower short arm of this lever are links 18, which inturn are connected on the rear end portion of one of the rods or shafts10. The rear end of the other rod or shaft 10 is connected by similarlinks to a depending arm on the opposite end of said rock-shaft. Thehandle portion of the said lever is provided with a pivoted pawl-lever21, which is designed to engage any one of a number of notches 21 in acurved templet 22, which is removably secured in a holder 23, secured tothe side of the machine-frame. When the hand-lever is in the positionshown in Fig. 2, with the pawl engaging the central notch of the templet22, the work-supports, no matter what may be the degree of separation oftheir jaws, will be in such a position that the center line of thework-support is directly underneath the punch. By shifting said lever tothe right both work-supports are moved bodily out ward, thus shifting toa corresponding extent the center line of the work with reference to thepunch, while a movement of said lever to the left will in a similarmanner shift the center line of the work inwardly with respect to thepunch. The positions of the hand-lever are controlled by the location ofthe notches in the templet 22, and diiferent templets will be employed,according to the nature of the work. By this arrangement it will be seenthat the work can be readily shifted to provide for staggered orparallel rows of punchings according to any given design, providedaproper templet is used. The longitudinal location of the holes isdetermined by means of templets 25, one of which is removably secured tothe upper portion of each of the jaws 8 in any suitable manner. In thedrawings I have shown the inner face (see Fig. 5) of these templets asprovided with a dovetailed recess 26, which is arranged to fit over acorresponding projection 27 on the jaws 8. Each of these templets isformed with a number ,of horizontal pin-holes 29 to receive a pin 30,such as shown in Fig. 8. The number and location of these holes willvary in each templet according to the particular arrangement of holes tobe punched or drilled in the work.

Referring to Fig. 3, and supposing the work to be introduced to themachine from the right-hand side, the pin 30 would be inserted in thefirst hole 29 in the templet at the lefthand side of the punch and thework would be moved through the machine until its end came in contactwith and was stopped by the said pin. It the location of this hole 29is, for instance, three inches from the center of the punch, it isobvious that if the punch now be operated the center of the hole mademust be three inches from the end of the work. The pin would then beshifted to the next hole and the work again moved into contacttherewith. If punching is to be done at both ends of the piece, afterthe left-hand end has been punched the pin would be shifted to thetemplet at the right-hand side of the punch and the work then moved backthrough the machine into contact therewith, the pin being shifted, asbefore, for each hole. The purpose, therefore, of providing one of thesetemplets at each side of the punch is to enable both ends of a piece ofwork to be punched in the machine without requiring the work to beremoved and turned around end for end. It is obvious that it a differentpunching is required for the two ends the two templets may have theirholes differently arranged, and, if necessary, after one end is punchedthe hand-lever may be operated to vary the location of the holes at theother end with respect to the center line of the work or to efiect astaggered punching. Where the work to be punched or drilled is ofconsiderable length, I provide in addition to the templets an extendedtemplet 31, a portion of which is shown in Figs. 3 and 6. This templetconsists of an elongated bar or plate one end of which is removablysupported on one of the brackets 6 and which extends laterally of themachine parallel to the line of movement of the work. In this plate areformed a series of holes to receive the pin in the salne manner as theholes 29 of the templets 25. For certain classes of work, however, whichwould not come in contact with pins inserted in these holes the upperedge of the said bar or plate is formed with notches 32 to receive amovable stop 33, which performs the same function as the pin 30. It isof course necessary to provide diiferent bars for difierent standards ofwork.

For the purpose of adjustment the holes ICC for the bolts 35, whichsecure .the brackets 6 v to the machine-frame, may be made oblong, and awedge-shaped piece 36 may be seated between the lower edge of thebracket and a bearing-piece 38. By slackening the nuts of the bolts 35and also the nut of the bolt 37, which secures the wedge-piece inplace/the latter may be moved to raise or lower the brackets.

The shaft 13 is preferably made in two sections connected by a coupling13 to facilitate the application and removal of the attachment to andfrom the machine.

It is obvious that while for purposes of illustration I have shown myinvention as applied to a punching-machine the construction,arrangement, and operation of the invention will in all respects besubstantially the same when applied to a drill-press, as a meresubstitution of the usual rotary drillspindle anddrill in place of thereciprocating punch-carrier and punch shown in the drawings in no wayaffects the invention.

I do not desire to limit myself to the particular construction,arrangement, and combination of parts which I have herein shown anddescribed, as it will be obvious that various changes may be made in thedetails thereof without affecting the spirit and scope of my invention.
